Example

Largest residual tumor nodule (mm)
2

Result: CC-1.

The tool opens with these values already filled in. Replace them with your own.

What the result means

Grade
largest residual nodule: CC-0 = none, CC-1 = <2.5 mm, CC-2 = 2.5 mm to 2.5 cm, CC-3 = >2.5 cm or confluence.
Complete
CC-0 and CC-1 are a complete cytoreduction (nodules <2.5 mm are within intraperitoneal-chemo penetration depth); CC-2 and CC-3 are incomplete.

What you enter

  • Largest residual tumor nodule (mm): 0 = CC-0, <2.5 = CC-1, 2.5-25 = CC-2, >25 = CC-3
  • Confluence of unresectable disease (forces CC-3)
